LABEL-SUPPLY MECHANISM FOR BOTTLE-LABELING MACHINES.

Specification of Letters Patent.

Patented Feb. 22, 1910.

Application filed August 7, 1909. Serial No. 511,683.

To all whom it may concern:

Be it known that I, EDWARD ERMOLD, a citizen of the United States of America, residing in New York, in the borough of Manhattan, county and State of New York, have invented certain new and useful Improvements in Label Supply Mechanisms for Bottle-Labeling Machines, of which the following is a specification.

This invention relates to improvements in bottle-labeling machines by which a regular and uniform supply of labels to the pickers is secured, and more especially to an improved label supply mechanism for the bottle -labeling machine for which Letters Patent No. 923,501 were granted to me on June 1, 1909. In the patent referred to a horizontal presser-bar was used for pressing on the tops of both piles of the labels in two label-receptacles, one for the body-labels and the other for the neck-labels. mechanism worked very satisfactorily when the piles of labels in the receptacles were of equal height, but when in working the bottlelabeling machine one pile or the other in said receptacles gradually became of different height, then an unequal pressure on the piles of labels resulted, so that sometimes more than one label was delivered tothe pickers at the lower end of one or the other receptacle.

The object of this invention is to' overcome this objectionable feature and to improve the label-supplymechanism in such a manner that each receptacle delivers its labels to its correspondin pickers independently of the delivery 0 the labels b the other receptacle, whether the piles of abels in the label receptacles are of uniform height or not; and for this purpose the invention consists of a label supply mechanism in which an upright pressenbar is arranged for each pile of labels in the label-receptacles, which presser-bars are guided independently of each other in separate holders guided on a stationary horizontal slotted guide-bar, said holders bein provided with pivoted and weighted paw s that engage ratchet-teeth of the upright resser-bars, the presser-bar for the body-la els being provided with recesses at its upper and lower end for guiding an auxiliary presser-bar rovided with guide-studs at its upper and lower ends and connected with the presserbar by an equalizing spring, so that each pile of labels receives an independent pressure This supply receivin the pile of neck-labels.

' war from its respective presser-bar, regardless of the quantlty of labels in the respective receptacles.

The invention consists further of certain details of construction and combinations of parts by which the upright presser-bars for the piles of body and neck labels can be adjusted relatively to each other and retained in raised position for replacing a new supply of labels in the label-receptacles, as will be fully described hereinafter and finally pointed out in the claims.

In the accompanying drawings, Figure 1 represents a side-elevation of my improved label-supply mechanism for bottle-labeling machines, Fig. 2 is a vertical transverse section on line 2, 2, Fig. 1, drawn on a larger scale and showing the presser-bar and auxiliary presser-bar for the pile of labels in the body-label receptacle, Fig. 3 is an elevation of the main and auxillary presser 7 bars, shown from the opposite side from that shown in Fig. 1, and Fig. 4 is a vertical transverse section on line 4, 4, Fig. 1, showing the presser-bar for the pile of necklabels, also drawn on a larger scale.

Similar letters of reference indicate corre-.

sponding parts throu houtthe several views. Referring to the rawings, A represents the upper portion of the frame of a bottlelabeling machine, B the sup orting bars for the label-receptacles C G 0 which two are arrangeda larger one C for receivin the pile of body-labels and a smaller one 1 for The labelreceptac es C O are composed of the parallel bars B and a number of 11 right fingersb that are supported on crossars b which are supported on the bars B. The finger-supporting cross-bars b are made adjustable on the horizontal bars B so as to ermit the adjustment of the label receptacfies for different sizes of labels, both for the bodies and necks of the bottles. The lower ends of the upriglht fingers 5 are provided with iny-projecting lips on which the piles of labels, which are placed in the receptacles, are supported. The fingers permit the free entry of the pickers p, 1 when they arrive in their position below the labelreceptacles so as to form contact with and take up the lowermost labels and remove them from the superposed pile of labels by the downward motion of the pickers. -The piles of labels in the receptacle 0, C are pressed downward by means of separate upfaces pass over t e right fpresser-bars d d one resting on the top 0 being guided independen y of each other in holders e, e that are supported on a horizontal and longitudinally slotted guide-bar 7 which is supported at the upper art of the supporting frame of the labe -receptacles, parallel with but centrally to the receptacle-supporting bars B. The holders 6, e are provided with side-recesses for being supported and guided on the bar f, and are rovided with clamping bolts e and nuts 6 y which the holders can be rigidly secured to the slotted guide-bar f after the upright presser-bars are placed in roper position at the center of'each pile of labels. I

At the opposite sides and upper ends of the holders e, e are arranged perforated ears 6 to which are, pivoted weighted paw-ls g, g which engage ratchet-teeth g g on the resser-bars, said teeth being so arranged that their upper horizontal faces are engaged by the awls while their inclined oints of the pawls as the iles of labels in t e label-receptacles are gra ually diminished, but that the presserbars are firmly held in position against pressure exerted in upward direction by the pickers on the lower ends of the poles. The resser-bars slide in downward direction by their own' weight as the pilesoflabels are diminished, but are held against pressure in the opposite direction by the weighted pawls g, 9 When the piles of labels in the receptacles are exhausted, the weighted pawls are swung on their pivots in upwardly-inverted position, and the resser-bars raised until projections g, g on the pawls engage recesses g, g in the resser-bars d, d for the body and neck-labe s, so that the presserbars are supported in raised positions and permit new piles of labels to be supplied to each receptacle independently of the other. When the resser-bars d, d are in raised position they are not in the way for supplying new labels to the receptacles. Each rece tacle feeds its own labels independently o the other by the independently-operating presser-bars.

Alongside of the u right resser-bar d for the pile of bodyabels is guided an auxiliary presser-bar d by means of headed guide-pins d at its upper and lower ends that are guided in recesses d at the upper and lower ends of the presser-bar d. The upper guide-pin (l is connected by a helical spring (2 with a stud-pin d on the presserbar (2. The lowerend of the auxiliary resser-bar d rests on the top of the pile of ody-labels and takes up the vibrations and shocks to which the body-label receptacle is exposed when the lpickers arrive below the same. The larger ody-labels are subjected to a greater degree of vibrations and shocks than the smaller neck-labels. These vibraeach pile of labdlsi said resser-bars By the arrangement of independent resser-bars, one for each label-receptacl a uniform supply of labels is secured to the pickers independently of the height of the piles of labels in the label-receptacles and the'shocks imparted to the same the feed of the labelsin one label-receptacle being independent of the feed of the labels in the other receptacle.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:
